# io.github.petrkrulis2022/touchstone-mcp

Dated SIU, the benchmark price of AI inference work: one free tool, three paid via x402.

- **Type:** MCP server
- **Trust:** 60/100 (B), scored on the content rubric
- **Verification:** community-indexed — nobody has claimed this listing
- **Version:** 0.1.0
- **Author:** io.github.petrkrulis2022
- **License:** Unknown
- **Endpoints:** streamable-http https://mcp.touchstoneassay.com/mcp
- **Source:** https://github.com/petrkrulis2022/dated-siu-inference
- **Endpoint health:** reachable (last checked 2026-09-25T22:16:56.588Z, 4 samples) — uptime is not a security property and is not part of the trust score
- **Compatible clients:** claude-code, cursor, copilot, chatgpt, gemini (basis: transport)

## Trust

60/100 (B), scored on the content rubric
- Publisher verified: no
- Install scripts: nothing suspicious found
- Prompt-injection scan: clean
- Obfuscation scan: clean
- Evidence age: 3 days

## Security scan

- **Status:** clean
- **Scanned:** 2026-10-02T01:39:51.657Z
- **Version scanned:** HEAD
- **CVEs:** no coverage — this entry has no package coordinates to query OSV against, so "no known CVEs" is NOT asserted for it.

## Tools

7 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `get_current_print` — Returns the current Dated SIU value, date, and status from the live, signed print.
- `explain_siu` — Explains what one SIU is: the basket, the quality gate, how the print is computed.
- `compare_model_cost` — Returns the current print's exchange-rate table — every constituent model's real cost, in SIU.
- `get_index` — Returns the current signed Dated SIU print.
- `get_quote` — SIU price and USD equivalent for one call of a task class against a model.
- `convert` — SIU + USD equivalent for a specific token count against a model.
- `verify_receipt` — Reads an on-chain settlement and returns a signed attestation of quoted vs. paid.

## Install

**Verdict: review** — Installable, but 2 things to check first: No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
**Cautions** (coverage gaps and advisories — never blocking)
- No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"touchstone-mcp\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.touchstoneassay.com/mcp\"\n    }\n  }\n}"
```

## Blast radius

Contained to moderate — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs on someone else's infrastructure; read-only tool surface.
- Floor 9, ceiling 27 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
